Nice find which nails it on the head, because so few people will subscribe for the service then the running costs of the scheme will be shared by fewer subscribers. The running costs must be quite considerable: staff to answer queries, stickers, website, processing payments etc etc. Expect the cost to rise to £60+ as charged by other boroughs and see even more people drop out and stick the waste at the bottom of the green bin.
It's simply more economic overall to provide this service funded from council tax (as may be mandatory in 2024 anyway) - just stick a quid or two on council tax.
The nasty side-effect is that recycling rates drop - london already has some of the worst rates in the country.
